STERLING - A teenage boy was killed in what officials called an "accidental shooting" at the home of an Illinois State Police trooper.

State Police Lt. Victor Markowski, the interim commander for Zone 2 investigations, said the shooting involved two teens and occurred about 11:40 a.m. Saturday. He said one teen who was not related to the trooper's family suffered a fatal gunshot wound.

Markowski declined to identify the teens, give their exact ages or provide further details on the shooting. He said the investigation was ongoing and that no more information would be available until Monday.

The Daily Gazette reports that Markowski said the investigation is not being treated any differently than normal despite the trooper's apparent involvement.
